When a hero image is loaded on an article, the whole page shifts downwards by a large degree. This unexpected layout shift can "disrupt the user experience in many ways, from causing them to lose their place while reading if the text moves suddenly, to making them click the wrong link or button. In some cases, this can do serious damage."

When using the Web Vitals browser extension by Google, the Cumulative Layout Shift (CLS) Core Web Vital metric on this page is measured to be at 0.36, which is rated as poor.

This issue did not exist in the previous article page design.
